Structure of Starch. Starch or amylum is a homopolymer (each yields only one type of monosaccharide (glucose) after complete hydrolysis) composed of D-glucose units linked by α-(1→4) glycosidic bonds.The α-(1→4) glycosidic linkage between the glucose units is formed by starch synthases.It is also called glucosan or glucan. α, β …
